Abstract

The invention is an Intelligent Conveyor Adjustment System (ICAS). The ICAS gives the user a way to adjust guide rails and other devices used in a conveyor system with actuators that can receive instructions based on a specific communications interface, such an interface may consist of but is not limited to serial wired network, an 802.11 compatible network, a power line network, and as described in the examples a wireless network, in a fashion to position rails or other devices on a conveyor system or in machines associated with a conveyor system. The actuators can be but are not limited to varying types, linear, rotary, push/pull covered cable, flexible strips, lever, pivoting, scissor, or other dual actuating mechanisms. The ACMs are used to control the actuators which control the relative position and shape of guide rails on the sides of the conveyor as well as position of various other conveyor entities such as, but not limited to, timing screws, labelers, marking machines, barcode readers, and fillers.

Claims

1. An intelligent wireless conveyor actuator system, comprising one or more IWCAS Segment Coordinator(s) (SC) and IWCAS Actuator Control Modules (ACM), using a wireless radio transceiver for transmitting and receiving instructions to actuators on a conveyor system.

2. An ACM of claim 1 which is attached to a guide rail and positions the guide rail according to the instructions from an SC.

3. An ACM of claim 2 that is coupled by electrical cable to another actuator (SA) attached to a guide rail opposing it that it controls the width between it and SA is controlled by signals from a ACM.

4. An ACM of claim 1 comprising:

a network interface in the case of a specific embodiment a wireless radio transceiver for transmitting and receiving control and functional information to and from SCs;

a control means for processing said received control and functional information and for outputting a control signal to one or more electrical or mechanical devices based upon said received control and functional information; and

a memory section for storing said control and functional information, the output signal, and said ACM'"'"'s own unique communications identifier. Said unique identifier is used to route information to one SC, said ACM is configured for communication to SCs within an actuator network or conveyor system

5. The ACM of claim 2 wherein said network interface, in the case of a specific embodiment a wireless radio transceiver, is configured for uni-casting, multicasting and broadcasting information.

6. The ACM of claim 1 wherein said control and functional information is routed based upon a location of an originating ACM or, alternatively, in a deterministic manner.

7. The SC of claim 1 wherein said memory section further includes a database of all of the ACMs within the conveyor segment, said ACM'"'"'s corresponding unique communication identifier and said ACM'"'"'s corresponding position along a conveyor line segment.

8. The ACM of claim 4 further comprising:

a timing means that is set to a predetermined threshold value, said predetermined threshold value is based upon a time that said ACM expects to receive said control and functional information from controlling SC units. When said timing means expires without receiving said control and functional information from the controlling SC unit, said ACM will broadcast a status inquiry to at least one neighboring SC or ICAS Supervisory Gateway (SG), and if a response to said status inquiry is not received, said ACM will transmit a communications error message to said other ACMs.

9. The ACM of claim 4 wherein at least one ACM broadcasts an error message to at least one other ACM, said at least one other ACM receives the error message, determines a type of error and transmits the error condition to another SC unit.

10. The ACM of claim 6 wherein said error message is given a higher priority for a communication channel than other periodic control and status messages.

11. The ACM of claim 2 where it moves the guide rail by using a push/pull, cable or flexible strips, to change the position of the rail.

12. The ACM of claim 13 where it moves a pair of push/pull cables to position both sides of a conveyor or multiple positions on a guide rail.

13. An intelligent conveyor actuator system of claims 1 to 12 where feedback information is recorded to calibrate actuators on a conveyor system

14. The ICAS of claim 13 where the calibration routine moves the actuators on the system to obscure a laser beam as a way to give feedback of the position of an actuator or guide rail.

15. The ICAS of claim 13 or 14 where the calibration routine gets feed back from a network interfaced DRO of which a wireless radio transceiver is one of several specific network interfaces that is positioned on the conveyor system.

16. The ICAS of claim 2, where the use of a flexible guide rail is used that has arcs pre-bent to a nominal radius.

18. The ICAS of claim 11 where the actuator(s) are used to adjust machine(s) on a packaging line.

21. The ICAS system of claim 1 where SCs can receive commands and exchange information with identified higher level controllers of the types of Human Machine Interface (HMI), Programmable Controller, Computer System, hand held device, intelligent cell phones.

19. The ICAS of claim 22 where there are rotary actuators and or Scissor type actuators are used to adjust machine(s) or rails on a conveyor line.

20. The ICAS system which utilizes a mix of network types with-in various areas of the system.

17. The ICAS of claim 20 where these pre-bent rails consist of two pieces of spring steal and they have been welded or attached at points to hold the nominal radius.
